If “The Universe Isn't Real..." Then What Is It?

[@TheSystemIsFlawed]

Most of this flew over my head but one thing I did get out of it was: Albert Einstein, a man whose name is synonymous with intelligence and scientific accomplishment, was wrong about something, yet his legacy isn't tarnished or belittled. Just shows it's OK to be wrong about some things, it doesn't discredit you forevermore

[@minimanadam]

Because he was rite about 1000x more than he was wrong

[@greenaum]

That's the point of science, all science is subject to later being amended, or even proved flat-out wrong. If you don't deal in that, your work isn't science.

[@zackakai5173]

To be fair, there's a BIG difference between being wrong because you were following a logical interpretation of data that testing later revealed to be incorrect (either because the data itself was incorrect or because you made a mistake somewhere in your interpretation that affected your conclusion), and being wrong because you were speaking out of your ass or were emotionally invested in some political/religious/ideological narrative.

[@earlofdoncaster5018]

Einstein has an annoying habit of being right even when he's wrong.

[@yanceyschwartz]

Science is not religion. Science is always changing and evolving. Just because Einstein improved upon Newton doesn't mean Newton was "wrong" or "tarnished" or "belittled" or "discredited". Newton will always be seen as a towering genius. Hundreds of years later we know more, so science evolves to accommodate our increased knowledge. Say a detective arrives at the scene of a crime-- they make an initial hypothesis based on the evidence available to them. As the evidence increases, their theory of the crime might evolve and change-- this doesn't mean they're stupid, it just means they're following the evidence. A lot of people just don't understand how science works. Perhaps most people.

*You did a good job describing it.* When I was in grad school I accidentally bumped into Bell's inequality while reading a QM textbook. I immediately recognized that it was special and took it to my professors to talk about it. Oddly enough neither one of them had ever seen it before and they took the day to look it up in order to verify it. Both men came back as elated as I was. This work cleared up for me a decade of headaches. Arguably the best thing I've ever read in a textbook.

[@paige-vt8fn]

It's kind of reminding me of quantum entanglement, being that after you read about Bell's inequality, the opposite was true with your professors, they knew nothing about it until of course until you told them about it. Does that mean that it doesn't exist or is less influential the less people are aware of something?? 🤔 I hope that made sense, it does to me. Science is AWESOME!

Problem is it can be done even better if physists didnt keep objecting like a political extremeist.

We have macro examples of these things. The Borh even said its an approximation being worked statistically due to not being able to isolate what you are looking at. So its just a matter of indirect information. Like sonar would be another example.

Another great example is memory metals now pretend when its liquefied we can't see it and we can see how it regains its shape. It doesn't do this because of math it does this because a mechanism. Mass is not a substance yet there is a lot of people that try to articulate as if it is. Masters is standard language in which we use to quantify things.

[@Steven-bs5hv]

Great video trying to make sense of a mysterious facet of reality. One way I've heard quantum properties explained uses a quantum information approach. Imagine an electron only has one bit to represent its spin, i.e., 1 = up and 0 = down or 1 = right and 0 = left. Which basically means if you measure an electron's up/down spin with a Stern-Gerlach device, the electron will consistently demonstrate its spin in the up or down direction (let's assume up), and if you then have a second Stern-Gerlach device and measure the same electron as left/right, the electron is forced to randomly choose its left or right response (let's assume right) to that measurement because it's currently using its only spin-bit to represent up from the previous measurement. Okay, so now let's measure the electron up/down again, and while you might expect its response to be up because the initial up/down measurement indicated up, you would be wrong 50% of the time. You can do this over and over again, and each time you change the orientation of the Stern-Gerlach device, the electron will randomly choose a new response in the new orientation. Bell showed that the realist notion (that the electron somehow knew it was spin up before the first up/down measurement was made) is incorrect because prior to being measured, the electron is in a superposition of all spins. Subsequently, when you have maximum certainty in one orientation, you have minimum certainty in a perpendicular orientation. So, when two electrons are entangled, i.e., represented by the same wave function, they can be thought of as sharing or splitting a spin-bit, and when one electron is measured as spin up, the other is necessarily spin down, and this correlation happens over any distance instantaneously at the exact moment that the wave function collapses due to a measurement, much to Einstein's chagrin. Any trained physicist can feel free to kick my butt on anything I got wrong.

[@edwardjenner1381]

"Any trained physicist can feel free to kick my butt on anything I got wrong." anyone that says this, as opposed to making a blanket statement, is probably 90%+ there. So, if the electrons share/split the same information and are part of the same wavefunction, are they even different 'particles'?

He just thought quantum mechanics was an incomplete theory, which it is, and was not the final theory. But he fully believed it worked.

[@manugott]

My question is how do they get particles entangled? Like how do you entangle 2 particles, and then send them away from each other to test the spooky action at a distance? Every body seem to just skip that part and I always find this part fascinating. Can you try explain that in a future video?

[@boltaurelius376]

Put them in your pocket, they will come out entangled.

[@scratchy996]

They use math. After all everything is just math. The two particles aren't even real. In the old days, they used a stick in a hole and a rope to spin a particle in one direction. They put each particle on the top of a stick, coiled the rope around it, tied the ropes to a cow , and used a whip to drive the cows in opposite directions.

[@craigtevis1241]

[@braindeveloperdimensional5579]

@@craigtevis1241 that's the most important part. Funny thing Indians called spheres Cow.

[@johnkooy5327]

My understanding is they are entangled and get them out of this state to measure 'the spooky action at a distance'. Anyway quantum physics to me is a fun new way to explain magic in a whole new way.

You almost make QM understandable. That's a huge compliment.

Well explained Joe. Thanks

[@mn-ru4li]

I just watched this documentary, called Everything Everywhere All at Once. Not only is the universe real, it's actually a multiverse. But none of that matters because there is no meaning, except that there is meaning. Also, sentient rocks do exists, so be nice to them. #family

Might be possible in your universe. Gonna test it out? 🤔

[@BLASTIC0]

Lol… Thats so weird… that Einstein was basically like…. “ you can’t just boil it down to a simple equation!” 😏

[@Ender240sxS13]

Describing physical objects and their properties with equations is one thing. But saying that the fundamental nature of reality is not made up of "physical objects" as we understand them but is actually composed of clouds of indeterminate probabilities which we can ONLY conceptualize as equations is a whole other thing. I'm a couple months away from completing a degree in aerospace engineering and by far the biggest struggle I have faced during that process was some of the electrical engineering courses where we have to deal with inherently quantum phenomena and therefore the behavior of these systems is described with probabilistic functions. Like I can fully wrap my head around advanced fluid dynamics problems, the multi-variable calculus is no problem, I can form a conceptual model in my head of the physical properties the different variables represent, and how the different operations model different physical phenomena and whatnot. When we use probabilities in those types of problems it's to represent our inability to perfectly measure certain values, it represents the uncertainty we have in a particular measurement. But when you start telling me that no, the physical thing we are working with can't be described with just a variable, it doesn't have a singular value but instead it exists as this probability function, and yes we can still describe the antennas and what not with these mathematical expressions but we have to plug this probabilistic expression into them and you aren't really going to get a value out you are going to get another probabilistic expression that describes your antennas response to those radio waves and you just then plug that into your decoder function and hey look you now have WiFi!!! It all just makes my brain kinda melt. Like seriously the mathematics and understanding that actually make things like digital radio communication and computer chips all actually work is some of the most mind boggling shit I have ever had to deal with, and I literally deal with the behavior of shockwaves inside rocket engines on a daily basis. And it all comes down to the fundamentally quantum nature of those things. Shits weird man.

[@squirlmy]

@@Ender240sxS13 When I first learned (in a very different context, namely, psychology) the there are blind spots on our retinas that eye movement and most importantly, brain processing of visual input, causes us to never notice, also that the brain projects the movement of some objects a couple of milliseconds ahead of time, so we can swing at a baseball or catch a pass... I came to appreciate that "Reality" is nothing like what we comprehend with our senses. Most of what we see, in particular, is an illusion, a magic trick.

[@squirlmy]

sorry, if my examples seem like a strange tangent. I'm saying that the reason you are weirded out by how wifi works or what goes on inside a rocket, is because naturally you expect it to work with the same physics as throwing a ball. But our visceral understanding of ball throwing, was always an illusion in the first place. Everything we thought we knew, is wrong.

[@greatoak7661]

Thank you! You really explained it in a way I can understand. That doesn't say much for you, but I really appreciate it. (joking) Seriously, until I watched this, I did not understand Bell's Test and what it meant. You included a lot of the "points" (couldn't help it) from the past that really told the story. The name following was brutal, I ended up just grouping them so I could stick to the knowledge. Thank you!

Joe - I applaud you for taking on this topic.

But I love it. And we love you. 😉

[@battlefieldcustoms873]

I like to imagine there are particles inside every one of us and maybe there is some science behind finding “the one” a person who you can entangle with

There is a great video made by Sabine Hossenfelder that covers the topics you've explained with more depth. She's a PhD physicist so it makes sense that she's able to cover it more thoroughly
